#2 - The Radio Set
The Secret Life of Machines - Season 2 - Episode 5

#3 - The Car
The Secret Life of Machines - Season 2 - Episode 1
Cars started to become popular in the 1890s. Their success was partly due to the bicycle, which had given people a taste for a personal means of transport. It was also due to Daimler's high speed engine, the first internal combustion engine to be small enough not to make a vehicle ridiculously cumbersome. Episode Contents: Models: A gutted modern body shell. A running car stripped down to the chassis. An exposed brake glows as it's applied. Machines: A mini that drives away from itself! Guests: A penny farthing and other antique bicycles. A 1902 Woolsey. Films: The cartoon life Daimler und Benz. Some quaint english promo films for early cars and lots of assembly line footage.

#6 - The Quartz Watch
The Secret Life of Machines - Season 2 - Episode 3
All clocks and watches work by 'counting' some event which takes a fixed period of time, like the swings of a pendulum. The higher it goes the stronger the pull of gravity and the faster it comes back - so the swings always take a fixed time. The Quartz crystal in a watch vibrates at a fixed speed in a similar way. Episode Contents: Models: A stick. Demonstration of liquid crystal technology with metal coated glass plates and polarized sunglasses. Machines: Many of Tim's large outdoor clocks. A water clock by Rex. Guests: A 400 year old pendulum alarm clock. Various antique pocket watches. Different watch models track the evolution of quartz and digital watches.

#7 - The Fax Machine
The Secret Life of Machines - Season 3 - Episode 5
The world's first fax machine was patented in 1843 by Alexander Bain. He came from a remote croft in Caithness in Scotland and, for his early experiments, used cattle jaw bones for hinges and heather for springs. His fax machine was based on an electric clock, which he had also invented. Episode Contents: Models: The "human fax" had Tim and Rex stand at opposite ends of a big field. Tim steps slowly over a sheet printed with giant letters of a message and uses coloured paddles to signal Rex who walks over a similar large sheet with a paint roller, applying paint when he sees the signal. Everything is synchronized with a metronome. The next model uses a board with nail at one each end which closes a circuit in contact with raised metal type. The current causes the nail at the other end to heat a sheet of paper soaked in potasium ferra cyanide. A "string fax" consisting of two drums shows how a picture can be transmitted one line at a time. The "lathe fax" uses a light detector hooked up to a buzzer which is then transmitted through the headset of a normal phone. A lathe at the other end has a sound switch which sends a current through the treated paper at every pulse from the sender lathe. The 2nd "human fax" emulates a digital fax with large grids placed over both Tim and Rex's sheets. Guests: A pair of French Pantelographe de Casell c.1860. A hydrogen balloon used for weather telemetry. A modern fax analyzer. Films: Cartoon life of Alexander Bain (patenter of the fax 150 years ago).

#8 - The Sewing Machine
The Secret Life of Machines - Season 1 - Episode 2
The first patent for a sewing machine was taken out by an English cabinetmaker called Thomas Saint in 1790. It's doubtful whether he actually built his design, because, when one was made from his drawings 100 years later, it had to be extensively modified to work. Episode Contents: Models: A giant human powered lock stitcher demonstrates the basic idea. A cut away singer shows how a crank powers all the basic functions. A demonstration of cams and stepper motors. Machines: Three of Tim's famous collecting boxes: The head scratching curator the rubber-necked guard and the doctor that writes out illegible prescriptions. There are some brief close ups of the construction of these machines. Rex also shows his magical remote controlled suitcase. Guests: A thumb crushing Thimmonier (the 1st practical sewing machine) Many antique decorative sewing machines. Films: The old Singer advert from the 40's is probably the funniest clip in this series. Extro: Say it in thread.

#12 - The Central Heating System
The Secret Life of Machines - Season 1 - Episode 3
At first Roman houses simply had a fire in the middle of the room (the Latin for hearth is focus).

The fire was lit outside in a furnace with hot air ducts under the floors and in the walls. Episode Contents: Models: Trying to start a fire with an electric drill. A Norman chimney vs a proper one.

#15 - The Video Recorder
The Secret Life of Machines - Season 2 - Episode 6
The principle of magnetic recording was invented by a Danish telephone engineer called Valdemar Poulsen in 1899.

All tape and video recorders still work this way. Episode Contents: Models: A band saw magnetic recorder. Recording a signal on scotch tape covered in rust (FeO^2) particles. A large model of a VCR type head and it's concentrative powers. Illustration of helical scanning.

Guests: An early Paulson wire tape recorder. A really impressive German "tapedeck" (c.1930) that used razor sharp steel bands running at high speed under high tension. An airplane black box. A 1940's German tape machine the Tonstreiber (sp?). Ampex VTR's at the BBC. A range of major domestic video formats. Films: The earliest video recordings.

#16 - The Electric Light
The Secret Life of Machines - Season 3 - Episode 3
A Scottish chemist called Joseph Swann tried passing electricity through fine wires (filaments) to make them glow white hot in 1860.

With no air left inside, the filament light bulb became a practical proposition. Episode Contents: Models: Some lightbulbs made by removing the air from milk bottles and adding graphite filaments powered by a welding power supply. Various experiments with phosphors.
